How to create a new channel with Faye, and then access it via a url or model?

Question

I'm using faye based on this tutorial to create a chat message system. The only thing is, I want different channels "chatrooms" that users can subscribe to by visiting their url. Also, I want to represent each channel with a model, so that I can find them by name or index. How do I do this? For some reason, I can't find any good resources on this. By the way, I'm not terribly new to Rails, I just don't know how to use Faye at all.

Here's my use case, just to be clear:

User visits my site.

User enters "chat1" into a form, which lets say accesses the Chatrooms controller, index action

Controller finds all Chatrooms by name "chat1"

If it can't find it, it instantiates a new chatroom called "chat1" and subscribes the user to it

Redirects user to that chatroom.

Faye seems to automatically create new channels when you ask to subscribe to them. In your javascript, instead of subscribing to "foo" for example, do this:

var channel_name = "/chatrooms/"+"<%= @chatroom.id %>";
    // Subscribe to the public channel
    var public_subscription = client.subscribe(channel_name, function(data) {
      $('<p></p>').html(data.username + ": " + data.msg).appendTo('#blab_box');
     });
